CASEIVIENT SASH.

Application filed May 81, 1922. Serial No. 564,792.

To aZZ whom it may concern.

Be it known that I, ERNEST A. PETERSON, a citizen of the United States,residing at Oakland, in the county of Alameda and 5 State of California,have invented certain new and useful Improvements in Casement Sashes, ofwhich the following is a specifi cation.

My invention is an improvement in windows, particularly of the typeknown as casement windows.

The object of my invention is to provide a means of locking the windowin anydesired open position in an ofiicientand posi tive manner as willsubsequently be de scribed.

Referring to the annexed drawing:

Figure 1 is a perspective view of my window.

Figure 2 is a transverse sectional view of my window with the sash inclosed position.

T igure 3 is a side view of the lower rider. Figure 1- is a side view ofthe upper rider.

Referring more particularly to the draw ing, the numeral 1 indicates acasement and 2 a sash. The casement 1 comprises horizontal members 3 and4 and vertical members 5 and 6.

members 9 and 10.

In the members 3 and 1 are secured hori* zontal V-shaped slide'ways 11and 12 respectively. A V-shaped rider 13 travels in the slide 11 andv arider 1% travels in the slide 12. The rider 113 has an upstanding post15 which projects into thelower end of the .member 7 within a socket 16.The rider 14: has a depending post 17 which extends into a socket 18 inthe upper end of the member 7. A slot 19 is cut in the member 7 runningfrom 'front to rear, and a vertical bore 20 joins the slot 19 and socket16. A

rod 21 fits within the bore 20, the lower end of said rod contactingwith the post 15 and the upper end projecting within the slotlS) andhaving a cap 22 thereon.

A lever 23 is pivoted in the upper end of the slot 19 and has projectinghandles 24 59 and 25 to actuate said lever. A downwardly projecting stud26 has a roller 27 pivoted thereto, said roller being adapted to engagethe cap 22 of the post 21.

A spring 28 surrounds the post 17 of The sash 2 comprises verti- 59 calmembers 7 and 8 oined by horizontal the rider 1.4 and is positionedbetween the upper end of member -7 andlthe rid-er 14:..

A rabbet in the upper surface of the sash allows for this arrangement. V

A link 30 is pivoted to the members 3 andlO and a link 31 is pivoted tothe members 9 and 4, thus linking the sash and casement together.

Suitable locks 32 and 33 on the inner and outer sides of the memher 8look the sash in its. closed position.

The sash 1s locked many open position in the following manner.

The handle 24 is swung downwardly which moves the stud 26 and roller 27into engagement with the cap 22 forcing the rod 21. downwardly andwedging the rider 13 in the slide 11. This downward movement also raisesthe sash slightly against the tension of the spring .28 which springholds the rider 1d wedged firinly'in the slide 12.

To release the sash the handle 25 is moved downwardly which swings theroller 27 away from the cap 22 and releases the pressure on the riders13 and 14:, when the sash may be moved as desired.

Having described my invention, I claim: I 1. A window comprising acasement and riders may be wedged inthe guide gI.0OV6S.

2. A window comprising a casement and a sash, links pivoted to theeasement and the sash, guide grooves 111 the easement. riders in saidguide grooves, said riders having posts projecting therefrom which fitinto sockets in said sash, a lever pivoted in said sash, said leverhaving a stud projecting therefrom, a rod engaging the post of the lowerrider and adapted to be engaged by said lever stud, a spring encirclingthe upper rider post and positioned between said sash and SttlClrider.

3. A look for casement windows having riders on the sash traveling inslides onthe.

casement comprising means to increase the normal distance between saidriders, said means includingv a manually operated lever. In testimonywhereof I afiix my signa ,ture.

ERNEST A. PETERSON.
